cds-question@unistra.frspectroscopic-binary-starsradial-velocitylate-type-starsThis paper is a follow-up of the vast effort to collect radial velocity data for stars belonging to the Hipparcos survey. We aim at extending the orbital data available for binaries with M giant primaries. The data will be used in the companion papers of this series to (i) derive the binary frequency among M giants and compare it to that of K giants (Paper II, Frankowski et al., 2009A&A...498..479F), and (ii) analyse the eccentricity-period diagram and the mass-function distribution (Paper III, Jorissen et al., 2009A&A...498..489J). Keplerian solutions are fitted to radial-velocity data. However, for several stars, no satisfactory solution could be found, despite the fact that the radial-velocity standard deviation is larger than the instrumental error, because M giants suffer from intrinsic radial-velocity variations due to pulsations. We show that these intrinsic radial-velocity variations can be linked with both the average spectral-line width and the photometric variability. We present an extensive collection of spectroscopic orbits for M giants, with 12 new orbits, plus 17 from the literature. Moreover, to illustrate the fact that the large radial-velocity jitter present in Mira and semi-regular variables may easily be confused with orbital variations, we also present examples of pseudo-orbital variations (in S UMa, X Cnc and possibly in HD 115521, a former IAU radial-velocity standard). Because of this difficulty, M giants involving Mira variables were excluded from our monitored sample. We finally show that the majority of M giants detected as X-ray sources are actually binaries.2009A&A...498..627Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/498/627CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/239 : The Hipparcos and Tycho Catalogues (ESA 1997)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/498/627https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/498/627http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/498/627https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/498/627https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/498/627http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/498/627GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/498/627/table2 (List of stars in sample II)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/498/627/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/498/627/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/498/627/table2?GETtext/xml+votable180.050000true3.650685620.20670170.0055555555555555566/349 765 919 959 1015 2040 2139 2618 2633 2826 2859 3011 3572 3892 3951 4039 4252 4270 4359 4367 4832 4920 4957 4968 5231 5533 5574 5667 5718 5721 6068 6267 6367 6440 6485 6719 6999 7253 7523 7545 7786 7977 8018 8085 8162 8207 8303 8430 8509 8556 8573 8611 8683 8753 8925 9128 9269 9285 9317 9589 10014 10471 10721 10737 10831 10879 10895 10916 10964 11017 11239 11382 11519 11544 11556 11704 11731 11874 11958 12207 12414 12506 12543 12565 12740 12770 12813 12882 13046 13311 13370 13392-13393 13454 13463 13494 13803 13887 13975 14048 14129 14328 14334 14363 14489 14501 14514 14696 14729 14753 14758 14826 14844 14936 14968 15006 15017 15088 15135 15196 15228 15429 15519 15659 15663 15670 15673 15899 15969 16171 16197 16263 16348 17119 17123 17210 17303 17474 17502 17546 17966 17968 18018 18184 18312 18470 18547 18657 18691 18702 18944 18998 19559 19606 19777-19778 19847 19879 20054 20082 20181 20235 20337 20395 21240 21268 21333 21464 21522 21765 21929 22027 22252 22418 22721 23536 23554 23757 23880 24557 25049 25206 25271 25340 25666 25769 25805 25909 25938 26068 26180 26232 26245 26317 26415 26423 26478 26543 26803 26825 27078 27301 27379 27546 27553 27662 27694 27788 27893 27978 28116 28587 29674 29939 30394 30772 31629 31682 31709 31905 31990 32085 32123 32277 32291 32311 32502 32509 32599 32621 32677 32689 36307 36317 36587 36655 36818 36851 40416 40566 40688 40730 44496 44747 44762 44774 44784 44822 44998 45043 48916 49008 49086https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/498/627?format=asciiOpticaldefaultJ/A+A/498/627/table2List of stars in sample IIrecnoRecord number assigned by the VizieR team.
